If the file system and files remain static, then this method implements an equivalence relation for non-null Paths. It is reflexive: for Path f, isSameFile(f,f) should return true.
File createNewFile () method returns true if new file is created and false if file already exists. This method also throws java.io.IOException when it’s not able to create the file.
